This invent-ion relates to machines 'for operstinr;r on shoes, sind is illustrated :is Aeinbodied inn inoeliine For cleaning the edges ot `fiber inserts suoli esnre sometimes ploeed 5 between tbe ontsoies sind Welts oi" slioes, 'partd ot the present invention is to snbstitnte nie- 20 ebonionily-operated cleaning menne for tbe lmnd tools now in nso.

An importent 'feature ot the invention is to be :lionnd in :i novel mounting; tor tbe genie ineniber, which is enrried on. nn erin overlisnpging tbe tool, in snob e manner that it may be swung boel; readily to ntiord oeeess to tbe tool.

To enable different parts tric with respect to the shaft 10. By this arrangement, as clearly shown in Fig. 3, different parts of the periphery of the gage roll project different distances beyond the edge of the cleaning tool 14, so that where the welt crease is comparatively deep one part may be used as shown in Fig. l, and where it is shallow, as about the heel, a portion projecting a lesser `distance can be used, as shown in Fig. 2, to insure effective engagement of the work with the periphery of the cleaning disk 14. of the periphery of the gageroll to be used as just described, the shoe is tipped relatively to the gage roll in theplane ofthe welt or rand crease. The gage roll turns in a plane parallel to the plane of rotation of the cleaning tool. Accordingly it will be apparent that the transverse re ation between the cleaning tool and the fiber insert will not be changed by variations in the lengthwise angular relation of the edge of the shoe bottom to the gage caused by tipping of the shoe and consequently such tipping will not have any tendency to` cause the cleaning tool to run off from the insert. Furthermore, since the gage roll is free to turn, the

` work maybe shifted from a position where the gage roll projects a relatively small distance beyond the edge of the cleaning tool to a position where theV gage lroll projects a greater distance beyond the cleaningtool, or vice versa, without causing any relative or rubbing movement to occur between the gage roll and the work, thus insuring against any damage to the finish of the portions of the shoe in the vicinity of the welt crease.

The gage is mounted on a plate 24, which can be swung upward (as shown in dotted lines in Fig. 4) to alord access to the tool 14 by turning a leaf spring 26 out of the Way. The plate 24 is pivoted to a support 28, which .may be adjusted vertically byan adjusting screw 30, and held by clamp screws 32. As

shown, the plate 24 is pivoted to the support 28 at a point somewhat above the lower end of the support, the arrangement being such that the portion of the support below the pivot serves to locate the gage in operative position in predetermined spaced relation to the tool 14, in which position it is yieldingly held by the leaf spring 26.

`The support 28 in turn is carried` by an overhanging arm 34 secured to the support 12 by a screw-and-slot connection 36 for adjustment longitudinally of the shaft 10.'

A brush 38, mounted on the shaft 1() ce `axially lwith respect to the tool 14, is provided for brushing away the particles of dried blacking removed by the tool 14.

In operation, after the trimmed edge of a shoe hasbeen coated with blacking and dried.

the shoe is presented to the above-described machine, and moved around with the welt crease in engagement with the roller gage 20.

until the cleaning tool 14 has loosened andV largely removed the dried blacking from the edge of the fiber insert. The shoe is then presented to the brush 38 for removal of any small particles of dried blackingthatmay still be left more or less loosely on the fiber insert. While an illustrative embodiment of .my invention has been described in detaiLit is not the intention to limit its scope thereby, or otherwise than by the terms of the appended claims.

Having described my invention, what I claim as new `and desire to-secure by Letters Patent of the United States is:

1. A machine for use in finishing welt shoes of the type having an insert between the welt and the outsole comprising, in combination, a cleaning disk having a perphery of a width equal to the thickness ofthe insert for operat ing entirely around the edge of the shoe bottoin after trimming to clean the edge of the insert, and a gage disk arranged in a plane parallel to the plane of the cleaning disk and having its periphery projecting beyond the periphery oi the cleaning disk for engagement within the welt crease of the shoe to guide the shoe as it moved relatively to the cleaning disk, the gage disk being spaced laterally from the cleaning disk a distance substantially equal to the thickness of the Welt to register the edge of the insert with the periphery of the cleaning disk.

2. A cleaning machine comprising, in conibinat-ion, a rotary disk having a narrow periphery :tor-'cleaning the exposed edge of an insert between the welt and outsole of a shoe without engaging the material at either side of the insert, and a gage disk mounted eccentrically with respect to the axis of the cleaning disk to 'turn freely in a plane parallel to the plane of the cleaning disk to ride along the welt crease to position the shoe to limit the operation of the tool to the material of the insert.

3. A machine of the class described coinprising. in combination. a rotary shaft, atool mounted on the end of the shaft., an arm overhanging the shaft, a. gage on the arm in immediate proximity to the tool and constructed and arranged to be swungr back to afford ready access to the tool. and yielding means mov able bodily into holding engagement with the gage to maintain the latter in predetermined spaced relation to the tool and arranged to be retracted from operative position to permit the swinging backof the gage.

4. A machine comprising, in combination,

a rotary shaft, a tool on the end of the shaft,`

5. A machine for operating on slices coniprising, in combination, a rotary disl; having a periphery to operate on a shoe, and a gage having portions disposed at varying distances troni the axis ot the `disk and mounted to turn freely about a fixed pivot to resist pre sure ot' the Work, the beingconstructed and arranged to perlnit port-ions ot the gage which project a desired distance tor use to be selectively utilized without varying the relation of the tool transversely with respect to 'the edge of the sole` 6. A machine for use in nishing `Welt shoes of the type having an Yinsert betiveen the Welt and the outsole comprising, in combination, a cleaning disk having a periphery ot' a Width equal to the thickness ot the insert for operating entirely around the edge of the shoe bottoni after trimming to clean the edge of the insert, and a gage dish arranged in a plane parallel to the plane of the cleaning4 dislr and having its periphery projecting beyond the `periphery oi' the cleaning dish t'or engage `nient Within the Welt crease ot the shoe to guide the shoe as it is inoved relatively to the Cleaningdisk, the gage disk being` spaced laterally troni the cleaning' dislt a distance substantially equal to the thickness ot the Welt to register the edge of the insert with the periphery of the cleaningr disk, and the gage dish being mounted eceentrically with respect to the cleaning disk so that by tilting,` the shoe about the periphery of the gage disk` `the amount of projection oi" the gage dish beyond the cleaning,` disk at the point ot' engagement with the ivorlr may be varied in accordance with variations in the de pt-li ot the Welt crease 7. il inachine for use in iinisliing slices having; liber inserts between the Welt and the sole comprising, in eon'ibination, a cleaning tool ot a Width to clean the edge of an insert Without inarring the adjacent Welt and sole, gagging ineans n'iovable to `and troni operative position to locate the shoe to register the edge o" the insert with the cleaningbiI tool., and means interposed between the tool and tliegaging means to liinit the inovenient oit the means to locate it in predetermined spaced relation to the tool.

8. iii machine for use in iinishing shoes having shoe bottoins the marginal portionsoil' which are ot laminated construction comprising7 in combination, a rotary iinishing tool otl a Width to tinish the edge ot one ot the coinponent layers ot the shoe bottoni without disturbiirfgthe adjacent edge oi.z another ot said layers, and a rotatable gage nieinber eccentrically inonnted with respect te the anis of the iinishingl tool and spaced troni the edge to be finished to register said edge with said tool. y i
